Find the absolute maximum value and the absolute minimum value of the following functions in the given intervals:

Answer :

It is given that

Now, f’(x) = 0

x = 4

Now, we evaluate the value of f at critical point x = 0 and at end points of the interval

Therefore, we have the absolute maximum value of f on is 8 occurring at x = 4.

And, the absolute minimum value of f on is -10 occurring at x = -2.
